How electronic leak detection works in Grovehill
Green roofs, ballasted roofs and roofs under paving are harder to test. What sits on the membrane can affect which method will work, and some may need lifting. We’ll discuss it with you when we quote. Drawings or details of the roof’s layers are useful because they show what’s under the surface. We will tell you if the roof can’t be tested. We survey single-ply roofs, roof terraces and balconies and green roofs, and the problems we’re asked to look at most are new roofs to check before paving or planting and holes left by work on the roof.
In a smaller place like Grovehill, some flat roofs sit in the open, so wind catches loose edges and trims. Felt and bitumen also age in strong sun. Splits, blisters and lifting edges are what to look out for. A flat roof that still holds water days after rain is also worth a closer look.
The report records the flat roof membrane as we found it on the day. That makes it useful now and a handy reference later, such as when you want to compare after future work.

Your questions about electronic leak detection in Grovehill
Is Grovehill within the area you cover?
We do. Villages and rural addresses get the same survey as a town house.
Is my home in Grovehill listed or in a conservation area?
We cannot confirm that for you, but Historic England’s list and your council can. A change of roofing material may need consent in either case.
Can you survey at the weekend?
We carry out surveys seven days a week. To find a day that suits you, ring 07833 053749 or send us an email.
How do I book a survey in Grovehill?
Just ring 07833 053749 or email us. After a few questions, we confirm the price and fix a day, weekday or weekend.
How soon will I get the report?
The Premium Survey report comes the same day, the Standard within 24–48 hours and the Basic within 48 hours. Each one is emailed.
Does ELD work under paving or planting?
On some roofs, yes. What sits on the membrane affects the method, so we check the build-up first.
Is this a RICS survey?
No. Our survey looks at the roof, not the whole building. If you need a full building survey, you will need a RICS survey as well.

What else we do in Grovehill
Honest limits
Before booking, it’s worth knowing what a survey will not do:
- Repairing the breaches (that’s for your roofer)
- Sections we can’t safely access
- How wet the insulation is
If you are not sure which survey you need, ring 07833 053749 or use the contact form and we will give you a straight answer. What a survey covers and doesn’t.
What this survey covers
- Roof terraces and balconies
- Green roofs
- Liquid-applied waterproofing
- Flat roof membranes
- Single-ply roofs
- Commercial flat roofs
What we’re asked to look at in Grovehill
When the membrane is buried, holes can’t be seen at all. ELD can work on some covered roofs though it depends on the layers.
Look out for signs like these:
- Holes around roof penetrations
- Leaks through a flat roof with no obvious cause
- Patched roofs that still leak
- Damp inside with no sign on the roof
If you live in an older home near Alexandra Road Congregational Church, the joins between later flat roofs and the old walls are where problems typically start.

What electronic leak detection looks like in Grovehill
Hemel Hempstead, which Grovehill is part of, is one of England’s post-war new towns. Homes from the post-war decades are common in the new towns, many with low-pitched roofs in concrete tiles and flat-roofed garages or porches. Many of those flat roofs have been re-covered over the years, and some may still have older felt. Cement sheet roofs on buildings from before 2000 may contain asbestos, so a specialist asbestos surveyor should check them before they’re disturbed. About 4.8 miles south-east lies High Elms Manor, a reminder of how long the area around Grovehill has been built on. On older houses around here, roofs often carry the marks of earlier repairs, from replaced slates to new lead, and any change of roofing material on a listed home needs checking with the council first.
If you let a flat or house near Hemel Hempstead station, the flat roof over a let home is worth a look before it becomes a tenant complaint. For site and facilities teams at buildings such as South Hill Primary School, large flat roofs, common on schools and other public buildings, need their outlets, upstands and coverings checked regularly.

Checking the roof from ground level
Look up at the roof after a storm, from the ground: broken slates or tiles in the garden, gaps along the ridge or loose lead are signs to note. Do not go up yourself.
After heavy rain, check ceilings and the tops of walls for new stains. Take a photo and write down when you saw it, which helps when we check the roof.
How the survey works
The aim of the visit is simple: to look at the flat roof membrane as closely as is safe and record what we find. Everything we note and photograph goes into the written report. It usually takes longer on a large roof than a small one, with the construction of the roof playing a part too. A visit to Grovehill is planned like any other: the time, the access and where to park are agreed beforehand. Visits can be on weekdays, Saturdays or Sundays. If there are outbuildings or garages you want looked at, mention them.
- You tell us about the roof and where water is showing.
- We check whether the membrane and build-up suit ELD.
- We choose a low-voltage or high-voltage method to match the roof.
- The membrane is tested and breaches are found.
- You get a report with photos of each breach.
Preparing for the visit
- Let us know where we can park nearby
- If the roof is shared, arrange access with whoever manages the building
- Leave side gates unlocked

What we look for on each type of roof
Inverted and paved roofs
We’ll tell you if your inverted or paved roof is not suitable.
Liquid-applied waterproofing
Liquid-applied coatings form a seamless layer, but can still have thin spots or holes. Whether ELD works depends on the coating and build-up.
